I think you need to re-think this one. A 'slurry' of metal particles is going to lubricate better than clean oil?? LOL! I don't think you understand how a hydrodynamic bearing works, nor do you appreciate how vanishingly thin the oil film is under load. |

I do intend to read the manual regardless but I really wanted to know how others drove their newer cars especially for breakin.

The threads that form the drain plug hole are not made of the same piece of steel as the pan. The drain hole threads are punched into a small rectangle of much thicker metal that's spot-welded to the inside of the pan. Check your oil pan (or find a loose engine in a wrecking yard and pull the pan off that). On either side of the drain hole, you'll find two small spot welds. These are the welds that hold the rectangle of metal in place. When you look at that rectangle from the inside of the pan, you can plainly see that it's made of much thicker steel than the pan itself. Honda (or its supplier) punches the hole in the rectangle, threads it, the welds it to the pan. The threaded rectangle on my original pan and the one on the new pan (installed 1994) were definitely of different thicknesses, with the new one being thicker. I believe Honda has changed the pans since 1991, and that's why we don't hear of stripped drain plugs nearly as often as we used to ten years ago. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

The thin part of the wedge is thin indeed, and contaminant particles must be small enough that they are smaller than the wedge, otherwise abrasion will occur. Consider that crankshaft main-bearing-to-journal clearance is on the order of 25-50 microns. The thickness of the thin part of the wedge will be less than that. I've read that a common automotive oil filter efficiency is about 30 microns, so you haven't got much there before wear occurs in the presence of metallic particles. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |
